(cuss-s) This invention relates to juice extractors, more particularly to juice extractors that are associated with food mixing devices having a poweroperated driving unit, and it has for its object 5 the provision of a simple, inexpensive and emcient device of this character;

This invention is a division of my copending application, Ser. No. 166,063, filed September 28, 1937.

1o Fpr a more complete understanding of this invention, reference should be had to the accompanying drawing in which Fig. 1 is a side elevation of a juice extracting device embodying this invention; Fig. 2 is an enlarged plan view of the 5 power unit used in the juice extractor of Fig. 1; Fig. 3 is an enlarged fragmentary view in side elevation illustrating a portion of the juice extracting device of Figs. 1 and 2, parts being'shown in section so as to illustrate certain details of go construction: Fig. 4 is a'fragmentary sectional view taken through the line 4-4 of Fig.- 3 and looking in the direction of the arrows; and Fig. 5 g

is an enlarged fragmentary sectional view taken through the line 5-5 of Fig. .3 and looking in 1 26 the direction of the arrows.

Referring'to the drawing, this invention has been shown in one form as applied to a juice extractor associated with the food mixing device described'and claimed in my above mentioned 30 copending application. As shown, a power unit i is provided which is used to drive the juice extractor. It will be understood that the power unit i0 is provided with a suitable electric motor .which is arranged to drive a plurality of shafts H arranged in a spaced-apart relation. There are-three of these shafts illustrated and they are used to drive three beater elements, as shown in my The power unit II when it is used to operate the juice extractor is supported on a suitable base i! with the shafts Ii projecting upwardly from the unit, as clearly shown in Figs. 1 and 3. A suitable hinge structure it is used to connect the 1 power unit to the standard l2. This hinge structure is described and claimed in my c pending application, Ser.

8, 1938. When the power unit is supported in this position, I prefer to use the central driving shaft Ii to operate the juice extractor. The juice extracting device arranged in accordance with this inventioncomprises a juice extracting or collecting bowl I! which is arranged to be positioned on 55 top of the power unit, as shown in Figs. 1 and 3.

above-mentioned copending application.

No. 228,971, filed September -The bowl II is provided with a' discharge spout i5a..

The bowl i! is-provided with an elongated central reentrant section it which receives the upwardly projecting shafts ll, asclearly shown in 5 Fig. 3. The bowl is further provided with a hoilow sleeve-like supporting and'spacing member I1 which surrounds the central shaft Ii. As shown, the member i1 is provided with an inwardly tapered section It at the top which fits into a. corresponding complementary tapered section It in the lower wall of the, juice collecting bowl I! to support the bowl I! in an elevated position above the power unit Ill.

The sleeve member I'I also is provided with a pair of spaced downwardly extending feet or pins i'la (Fig. 4) which arereceived in a pair of spaced sockets. Illa that are provided for them in the .power unit 'II on opposite sides of the central driving shaft 1 I. These sockets function to sum port the sleeve member i1, and hence the juice extracting bowl I.

Positioned within the juice extracting bowl ii is a juice extracting reamer 2. which has a driving shaft ii that extends downwardly through the sleeve supporting member i'l so as to have a driving connection with the central driving shaft H As shown more clearly in Fig. 4. this central driving shaft II is hollow at its upper end and this hollow and receives the driving shaft ii of 80 the reamer in telescopic relation. The driving j shaft 2i isprovided with a pair of driving ears or lugs 22 positioned onopposite sides of the shaft and received in slots 28 positioned in opposite sides of the upper end of the central driv- 86 ing shaft 'li so as'to effect a drivingconnection between the two shafts. v

The shafts H carry suitable collars 24 which are used to lock the driving spindles of the beater elements to the shafts, as described and claimed 40 in my copending application Ser. No 228,972, filed September's, 1938. .These collars perform no function in the instant application because the driving connection betweenthe reamer 20 and 'theshaft ii is effected solely by means of the ,5 driving lugs 22 and the slots II which receive 4 them.

The reamer It carries a centrifugal straining member II which is arranged to extract the juice -from the-=puip and seeds by centrifugal action as so the reamer rotates. i

Cooperating with the reamer is a cup-shaped fruit holder 10 having an impaling member 21 which secures the half fruit in the cup. The cupitissupportedbyanarmilwhichispiv I6 passes freelyw throug anaperture tions together thereby to lock the standard u ism a. The standard a at its lower end is provided with spaced-apart parallel channels '30 (Fig. 5). The channels 30 are arranged to slide on a pair of parallel flanges It in ii-lha slib ii s@9 1 nd se. a its inner end threaded in the other end section so that it may .be turned in to force the end secv the flanges 3|. s It will be understood that when it is to operate the juice extractor, melee unit Hl' is placed on the standard IZ'in" its position 7 shown in Figs. 1 and 3. The support I! is then placed on the power .unit with itstwopins Ha k: inserted in the sockets la,- and"then the -"Juicer bowl is placed on the support. The reamer may then be placed in the bowl in driving-relation with the central shaft H. and then the fruit holderstandard 29 will be attached to the channels 3| and locked by the screw member I3; ,Thehalf fruit is then placed within the cup 28 and is brought into extracting relation with the reamer by pivoting the arm 28 down wardly toward its position shown in Fig. 3. The Juice which is extracted is separated from the seeds and pulp by means of the strainer 26 an is discharged through the spout Ila.

I While I have shown a particular embodiment of my invention, it will be understood, of course, that I do not wish to be limited thereto since many modifications may be made, and I, therefore, contemplate by the appended claims to andhas "operative 'positi shai'ts.
